In today's digital landscape, automated testing plays a crucial role in ensuring the functionality of web applications. One common task in web testing is verifying whether specific text appears on a webpage. In this article, we will walk through how to accomplish this using the Robot Framework combined with Selenium.
Understanding the Problem
When performing web testing, you might need to confirm that certain text content (like messages, labels, or other informative texts) is present on a web page. This is important for ensuring that the application displays the correct information to the user.
The challenge lies in implementing a robust method to check for text presence without causing unnecessary test failures or overlooking critical information. We will demonstrate how to leverage Robot Framework, which is designed to provide a keyword-driven approach for testing, along with Selenium for web browser automation.
Scenario and Original Code
Imagine you have a web application, and you want to verify that a welcome message, "Welcome to Our Website", is present on the homepage. Here’s how the scenario can be implemented using Robot Framework and Selenium.
Initial Code Example
*** Settings ***
Library SeleniumLibrary
*** Variables ***
${URL} http://example.com
*** Test Cases ***
Check Text Presence
Open Browser ${URL} Chrome
${is_text_present}= Page Should Contain Welcome to Our Website
Close Browser
Analysis and Clarification
Key Components of the Code
-
Settings: We import the
SeleniumLibrary, which provides the necessary keywords to interact with a web browser. -
Variables: The URL of the webpage to be tested is stored in a variable for easy reference.
-
Test Cases: A test case is defined to open the browser, navigate to the specified URL, check for text presence, and finally close the browser.
Using Page Should Contain
The keyword Page Should Contain is a built-in keyword from the SeleniumLibrary. This keyword asserts that the specified text is present on the page. If the text is not found, the test fails, providing a clear signal that something may be wrong with the webpage or the content it displays.
Best Practices for Text Verification
- Case Sensitivity: Be mindful of the text's case (uppercase/lowercase) when checking for presence. Consider using the
Should Containkeyword for a case-insensitive check. - Dynamic Content: If the text changes based on user interaction or other conditions, ensure your test accounts for this variability.
Structuring for Readability and SEO Optimization
To ensure that our article is not only informative but also optimized for search engines, we utilized subheadings, bullet points, and keyword-rich phrases like "Robot Framework", "Selenium", "check text presence", and "automated testing".

Conclusion
Verifying the presence of specific text on a webpage using Robot Framework and Selenium is a straightforward yet essential task in web testing. By implementing the provided code and considering best practices, testers can enhance their testing suite and ensure high-quality web applications.
By following this guide, you should now have a clear understanding of how to check if a text is present on a webpage. Happy testing!
Remember, continuous learning and experimentation with automated testing frameworks are key to improving your testing skills. For more advanced implementations, consider integrating with Continuous Integration (CI) tools or expanding your test coverage.
